AS STUBBORN AS MULE-ODY

While having dinner, Lyrical suddenly remembered what Edwina had told her, when she narrated the incident that happened with Melody back when they were studying. That's the reason why Melody becomes suicidal on her birthdays. Melody did not have the habit of sharing her problems with anybody, and Lyrical was unable to connect the dots. That made Lyrical feel anxious, afraid that she might have been one of the reasons why Melody was suffering so much. 

If what Edwina said is true, that means whatever happened that day should've been very gruesome, because Lyrical clearly remembered that Edwina had mentioned Melody was bruised that day and was crying because she had lost someone dear to her.
